RAIL-SUPPORT.

To Lil/[whom it may concern:

Beit known that I, J ULIEN CHAPrU'Is, engineer, a citizen of the Republic of Switzerland, residing at Bienne, Switzerland, have invented certain newand useful Improvements in and Relating to Rail-Supports, of which the following is a specification.

The invention relates to improvements in rail-supports, and more particularly to the sleepers or cross-beams bearing the rails.

The invention consists in making the said supports or cross-beams of a suitable structure of armored concrete and of providing the same with suitable devices for connecting and fastening'the rails to the said sleepers or supports of armored concrete.

The general structure of the device may vary according to circumstances; but it will as a rule be formed of a solid block of con crete in which suitable iron or steel wires or' bars are embedded, so as to distribute the pressure which is transmitted to the device by the railswhen a train is passing over the same as far as possible to the whole of the said support and by-itto the ground. For this purpose there will be preferably buried or embedded in the block of concrete several longitudinal iron or steel wires or bars intended. to act .by tension against transverse breaking strains, and several wires or bars are also placed in a transverse and diagonal direction in the block of concrete with aview "-of transmitting the transverse strains into a longitudinal strain on the concrete mass. The solid block of concrete is provided with suitable depressions and projections-to form two bases receiving the chairs or rail, and suitable'w'ires maybe buriedi'ii or adjacent to the pertions of the said block where the said. de-

' 1y consolidate the same.

pressions or projections are made, so as to suit- The said solid ock of concrete is further provided with suitable holes and'cavities into which the screwbolts and keys nay be located which are intended to fasten the rails to the sleeper or support.

It is obvious arrangement of the wires or bars and of the depressions, projections, holes, and fcavitic's in the same is capable of modificationin various ways to suit particular requirements at the left-hand side a treenail connection of the rail and at the right-hand. side a screw-bolt connection of the same to the sleeper or crossbar. Said figure shows at the left-hand side a projection a cut through at the line C D of Fig.

2. Fig. 2 is a plan view of the sleeper or cross-bar shown in Fig. 1. Fig. 3 is. a crossseetion of the sleeper or cross-bar on the line A B of Fig. 1.

treenailed fastening instead of a bolted fastening. Fig. 5 is a front elevation of a modified construction of the sleeper with portions broken off to show the inner construction of same. Fig. 6 is a section on the line A B of Fig. 5. Fig. 7 shows separately in top view the plate f and fitting g of Fig. 5.

The body a of the sleeper or cross-bar is of the same size as the usual wooden ones. It is der said wires or ars b and 0 in the manner shown in said figure. The same armoring is ap plied to the'project na of the sleeper or cross-bar of the fished rails as shown at the left-handside of Figs. 1 and 2. The projec- Fig. 4: is a similar section to that on. the right-hand side of Fig; 1, showing a tion a shown at the right-hand sideof' said figure is intended to support the rail to the joint when the railway-track is to be constructed with floating joints, while the projection a supports the joint itself, as shown in that the construction of the above-mentioned solid concrete block andythe Fig. 2. To allow the rails to be connected to this girders, thejgirder is provided at certain places with suitable holes in which are located suitable woodenblocks d, Fig. 4E, surrounded with wire it inttihdEdt'Wpr-event the said wooden blocks from splitting, and said wire is allied to the concrete in the same manner as the armor of the body of the sleeper itself. Each Wooden block is provided with a hole of the usual diameter, and an octagonal treenail is driven into the same.

If the fastening of the rails is to be made by means of screw-bolts, suitable holes are made througl the whole girder, and supporting pIates or washers g, Fig. 1, are combined with the concrete in order to receive the bolts, and suitable wires may be placed in the concrete around the said holes, so as to prevent any disaggregation of the same.

In theconstructlohslidwn in Figs. 5 to 7 the sleeper a is provided with suitable recesses an, intended eceive the bolts e, which are provided witliaped heads. Each of the said recesses o *avities a is provided, on the one hand, with a metallic plate or wasl having an outcut f, as s1owii""separately in Fig. 7, and, on the other hand,with afitting 9, formed of a curved piece of sheet metal, both being suitably incorporated within the concrete forming the sleeper-body.

The plate or washer f is intended to support the T-shaped head of the bolt 0, and the fitting g is intended to prevent the bolt e from injuring in any manner the concrete walls of the recess a.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. A rail-support, composed of a material molded to shapewhile in a plastic condition, having embedded therein two sets of longitudinal metallic rods, one set in proximity to its upper surface and one set in proximity to its lower surface, and each set consisting of a plu* molded to shape while in a plastic condition,

substantially of rectangular shape and provided with projections extending some distance from the body of the support in line-with the rail, an upper and a lower set of longitudinal metallic rods embedded in said support and projections of the same, and wires in Z'igzag arrangement passing from the upper rods to the lower rods, successively enveloping one rod after the other, substantially as described.

3. A rail-support, composed of a material molded to shape while in a plastic condition, provided with holes, spirally-wound wires embedded in the walls forming the holes, and wooden blocks in said holes, substantially as described.

I; In combination, a raihsupport, composed of a material molded to shape while in a plastic condition and provided with holes, rails on said support, plates provided with holes embedded insaid support and arranged transversely to the holes of the same, bolts passing through the holes of the plates connecting the rails-and the'plates, and metallic fittings interposed between the rails and transverse plates and surrounding the bolts, substantially as described.
